MySQL同步故障:" Slave_SQL_Running:No" 两种解决办法

进入slave服务器,运行:

mysql> show slave status\G

Relay_Log_File: localhost-relay-bin.000535
Relay_Log_Pos: 21795072
Relay_Master_Log_File: localhost-bin.000094
Slave_IO_Running: Yes
Slave_SQL_Running: No
Replicate_Do_DB:
Replicate_Ignore_DB:

 

解决办法一、

Slave_SQL_Running: No
1.程序可能在slave上进行了写操作

2.也可能是slave机器重起后,事务回滚造成的.

一般是事务回滚造成的:
解决办法:

mysql> stop slave ;
mysql> set GLOBAL SQL_SLAVE_SKIP_COUNTER=1;
mysql> start slave ;

 

解决办法二、

首先停掉Slave服务:slave stop
到主服务器上查看主机状态:
记录File和Position对应的值

进入master

mysql> show master status;
±---------------------±---------±-------------±-----------------+
| File | Position | Binlog_Do_DB | Binlog_Ignore_DB |
±---------------------±---------±-------------±-----------------+
| localhost-bin.000094 | 33622483 | | |
±---------------------±---------±-------------±-----------------+
1 row in set (0.00 sec)

 

然后到slave服务器上执行手动同步:

mysql> change master to
master_host=‘master_ip’,
master_user=‘user’,
master_password=‘pwd’,
master_port=3306,
master_log_file=localhost-bin.000094’,
master_log_pos=33622483 ;
1 row in set (0.00 sec)
mysql> start slave ;
1 row in set (0.00 sec)

mysql> show slave status\G
*************************** 1. row ***************************
…
Master_Log_File: localhost-bin.000094
Read_Master_Log_Pos: 33768775
Relay_Log_File: localhost-relay-bin.000537
Relay_Log_Pos: 1094034
Relay_Master_Log_File: localhost-bin.000094
Slave_IO_Running: Yes
Slave_SQL_Running: Yes
Replicate_Do_DB:

 

手动同步需要停止master的写操作!
